P R E L I M I N A R Y Z86193 CPS DC-4206-01 PRELIMINARY CUSTOMER PROCUREMENT SPECIFICATION Z86193 CMOS Z8® MICROCONTROLLER MULTIPLIER/DIVIDER/SEARCH/MERGE GENERAL DESCRIPTION The Z86193 is a CMOS ROMless Z8® microcontroller enhanced with a hardwired 16-bit x 16-bit multiplier, 32-bit/16-bit divider, three 16-bit counter/timers, search and merge instructions, Evaluation mode and a Bus Request mode. The device is code compatible with other Z8 family devices, yet it offers more powerful mathematical capabilities, data searching capabilities, and bit manipulation. The Z86193 is offered in a 64-pin VQFP package. The Z86193 provides up to 16 output address lines permitting an address space of up to 64 Kbytes each of Program or Data memory. Eight address outputs are provided by a de-multiplexed 8-bit Address Bus (A7-A0) or by a multiplexed 8-bit Address/Data Bus (AD7-AD0). The remaining eight address lines (A15-A8) can be provided by the software configuration of Port0 to output address. The Z86193 includes a bus which differs from other Z8 devices. The Z86193 provides bus control signals /RD (Read Strobe), /WR (Write Strobe), and ALE (Address Latch Enable). There are 464 8-bit registers located on-chip and organized as 444 general-purpose registers, 16 control and status registers, one reserved register, and up to three I/O port registers. The Register File is partitioned into two Register Pages. Page0 contains 208 registers and Page1 contains 208 registers. The 48 other registe...
